javascript - Append class with if statement -

i created variable specific site of mine want append class entitled "partner-text" if i'm on site. if i'm on different site don't append it. how can that?

use(function() { var inpartnerpath = currentpage.getpath().indexof("partners_skate_daily"); // check if site under partners_skate_daily folder if yes should return true  var ispartner = (inpartnerpath != -1) ? 'true' : 'false';  return {     ispartner: ispartner };  }); 

'true' , 'false' strings. want use boolean values true/false.

you don't need ?: here, != already returns boolean.

var ispartner = inpartnerpath != -1;
